A friend recently bought a new CZ rifle in .300 Win Mag. I don't remember the model, but it's a beautiful rifle. I know he paid a pretty penny for it.
He reloads and has a favorite load for his old rifle, using 180 gr. bullets. He worked and worked with it in the new CZ but couldn't get consistent accuracy at all. He likes long-range hunting and is a good shot. He said he finally called CZ, and they told him that his new rifle has too slow of a rifling twist to stabilize 180 gr bullets, and they couldn't guarantee accuracy with anything over 170 gr.!!
I've never heard of such a crazy thing. It's hard for me to imagine anyone making a .300 Win mag that won't shoot 180 gr. loads. He said he never would have bought it had he known that, but he'll get some 165's and see how they work.
